INL: IP Networking Lab - wifi roaming

dleroy — Mon, 04 Jan 2010 16:53:28 +0000

La ville de Nivelles a annoncé il y a quelques mois son intention d'adhérer au projet FON [1,2], un projet de partage de WiFi communautaire. Ce qui peut s'apparenter à une très bonne idée au premier abord, pose pas mal de questions à la fois techniques et juridiques. N'étant pas juriste, je ne ferai que mentionner les côtés juridiques, sans entrer dans leurs détails.

Authenticated Wireless Roaming via Tunnels: Making Mobile Guests Feel at Home

In wireless roaming a mobile device obtains a service from some foreign network while being registered for the similar service at its own home network. However, recent proposals try to keep the service provider role behind the home network and let the foreign network create a tunnel connection through which all service requests of the mobile device are sent and answered directly by the home network.

WiFi Roaming: Legal Implications and Security Constraints

dleroy — Mon, 10 Nov 2008 16:10:13 +0000

WiFi technology has become the preferable form for mobile users to connect to the Internet. The growing popularity of WiFi-enabled devices and the increasing number of WiFi networks guarantees that this trend will continue in the future. Since a single network provider is usually not able to ensure WiFi coverage for its own users across many geographic locations the WiFi roaming technology appears to be the promising solution. A special attention upon the practical deployment of WiFi roaming should be paid to possible threats coming from the misuse of technology.
